Joints can handle some heavy pressure.
For example, knees handle a force of three to four times a person’s total body
weight on average when just taking a walk. The force of a deep knee bend during
a squat can increase to nine times the body weight.
So just imagine multiplying weight of more than 150 pounds times a minimum of
three or four, and then even more. That can sure add up to a lot of heavy work
on knee joints over time.
Now for the science of this scenario. Where two bones meet, called the joint,
the bone ends are covered with cartilage, also known as gristle. This cartilage
is sturdy, elastic and spongy or compressible
,and keeps the bones from moving against each other at the joint. The cells of
this cartilage, called chondrocytes, are thought to be the longest living cells
of the body.
Surrounding the bones and cartilage is strong, fibrous capsule lined with
synovium, a thin membrane that lubricates the joint area with fluid. The end
result is less friction or smoother rubbing together of the bones. This fluid
also feds the cartilage cells, keeping them healthy, and is pumped into them
during joint movement.
Thus lack of movement (activity / exercise) can be unhealthy.
Other parts of the body features involved with this arthritic scenario include
muscles, tendons, ligaments, bursea and mental activity. Muscles, attached to
bones with tendons and ligaments, move bones by contracting.
They also cushion movement, absorbing impact or shock. Throughout the muscle and
tendon areas are bursae or sacs filled with fluid.
These also help cushion movement. and throughout all the coordination of these
parts during movement, the brain is a part.
The brain communicates via nerves throughout the body, in particular the muscles
for this scenario, to prepare joints for activity. The exact science of what
actually causes arthritis is still being researched. For most of the 100-plus
forms of arthritis, the causes are unknown.
Injury, overuse of joints and mechanical issues with joints (like skeletal
abnormalities, worn out joint muscles) can lead to arthritis. And many point to
issues relating to bacteria and germs as some of the problem. Heredity, stress,
drugs, food allergies and viruses have also been linked to some forms of
arthritis. So have diet, poor circulation and lack of movement.
INFLAMMATION
Arthritic joints can be affected with inflammation when bacteria or a virus (or
other undesirable element) enters the joint area or when an injury occurs. What
happens is when foreign matter enters this area or the area sustains injury,
white blood cells, antibodies and other natural fighting mechanisms
automatically kick in internally to help. These fighters cause swelling, redness
and heat as the body fluid moves around. Symptoms of inflammation, one of the
uncomfortable issues associated with arthritis, are redness, swelling and tender
joints.
